ABSTRACT:
A control circuit for an active engine mount is provided, including an electrical bridge circuit, and a pulse-width modulation (‘PWM’) circuit. The PWM circuit receives an input signal from a controller, and generates first and second PWM output signals. The first PWM signal, derived from the input signal, controls first and third switches of the electrical bridge circuit. The second PWM signal comprises a digitally inverted signal of the first PWM signal, and controls second and fourth switches of the electrical bridge circuit. First and second outputs of the bridge circuit are connectable to first and second terminals of the mount device. The controller receives an input signal from crank and cam sensors, as part of the control scheme.
